A disaster recovery plan is a documented process or set of procedures to recover and protect a business IT infrastructure in the event of a disaster. Having a comprehensive disaster recovery plan is essential for any organization to minimize downtime and data loss. An effective disaster recovery plan should include the following key elements:
Business impact analysis
The first step in developing a disaster recovery plan is performing a business impact analysis (BIA). The BIA helps identify time-sensitive or critical business functions and processes that should be prioritized in the plan. A BIA typically involves identifying:
- Key business functions and processes
- Recovery time objectives (RTOs) – the maximum tolerable time a process can be down after a disruption
- Recovery point objectives (RPOs) – the maximum tolerable period in which data might be lost from a disruption
- Dependencies – internal and external partners, suppliers, or resources a process depends on
- Potential financial, operational, and legal impacts of disrupted processes or systems
Documenting this analysis highlights the business impact of various disaster scenarios, which allows an organization to determine disaster recovery priorities and objectives.
Emergency response procedures
The disaster recovery plan should outline steps to detect and respond to a disaster in the initial minutes and hours. This includes:
- Defining escalation procedures – who is notified, when, and how
- Assembling a response/recovery team with defined roles and responsibilities
- Assessing the type and extent of the disaster
- Initiating emergency controls and measures to minimize immediate impacts
- Mobilizing recovery resources, facilities, and vendors
Well-defined emergency response procedures facilitate rapid decision making and action during chaotic or stressful conditions.
IT disaster recovery procedures
Detailed IT disaster recovery processes and procedures should be documented based on scenarios identified in the business impact analysis. This includes steps to restore IT operations for critical systems, networks, hardware, and information repositories. Key elements include:
- Backup and restoration procedures
- Failover/switchover processes
- Replication methods to protect and recover data
- Use of alternate or spare IT infrastructure
- Resources required to recover/rebuild each system
- Roles and responsibilities matrix for IT response personnel
The procedures should provide a step-by-step IT disaster recovery manual tailored to the organization’s needs.
Communication procedures
The plan should establish procedures for communicating with relevant parties during the disaster, including:
- Contact information for disaster recovery team members, executives, employees, and key external stakeholders
- Distribution methods for status updates (email, text messaging, social media, etc.)
- Communicating recovery status to customers, partners, authorities, and the public
- Locations and responsibilities of public relations teams managing external communications
- Secure channels for communicating sensitive information internally
This facilitates coordination and helps avoid confusion by disseminating clear, actionable information to those who need it.
Roles and responsibilities
The disaster recovery plan should clearly define roles and responsibilities before, during, and after a disaster scenario. This includes:
- Identifying a disaster recovery coordinator and team members
- Documenting roles for IT, facilities, human resources, communications, procurement, security, and executive leadership
- Defining responsibilities for liaising with external stakeholders, authorities, and vendors
- Delegating staff to compile damage assessments, oversee repairs, and manage claims/insurance
- Designating roles for logistics, transportation, shelters, and supporting personnel resuming onsite operations
Each role should have clearly articulated responsibilities for efficiency and accountability during the disaster recovery process.
Third party providers/vendors
The plan should identify third party vendors or service providers critical to business operations. Information on third parties that support systems, provide infrastructure, or perform outsourced business processes allows an organization to assess the potential impact of a disrupted vendor. Key vendor information includes:
- Contact information
- Goods or services provided
- SLAs, performance metrics, and contractual disaster recovery provisions
- Alternate vendors to replace third party services if needed
Third party assessment ensures the organization can react quickly if vendors experience operational disruptions.
Physical facilities
For recovering critical business locations, such as data centers, headquarters, and branch offices, details on facilities should be documented. This includes:
- Locations, sizes, and purposes of facilities
- Floor plans and equipment layouts
- Capabilities and capacity for supporting operations at alternate sites
- Facilities systems information – power, cooling, networks, security
- Requirements to recover physical infrastructure at each site
This facilitates restoration of impacted facilities or transfer of operations to alternate sites.
IT hardware equipment
IT hardware assets supporting critical information systems and services should be inventoried. An up-to-date asset inventory helps accelerate procuring emergency replacements if needed. Inventory details include:
- Hardware model numbers and configurations
- Hardware functions and applications supported
- Locations and quantities of devices
- Requirements and lead times for acquiring replacements
- Vendor or reseller information
Accurate inventory information aids rapid recovery of disabled IT hardware systems following a disaster.
System configuration/architecture documentation
Current configuration information on critical technology systems, applications, and data repositories simplifies restoring systems to a stable state after disasters. Configuration documentation should provide technical specifications such as:
- System architecture diagrams
- Hardware and software dependencies
- All components in server configurations
- Application installation/configuration parameters
- Data flows/interfaces between systems and databases
- Access requirements and credentials for systems
Thorough documentation helps recreate or repair damaged technology infrastructure.
Insurance documentation
Maintaining current insurance documentation is key for replacing assets, compensating costs, and assuring financial resources for recovery. Insurance details should include:
- Inventory of insured assets, equipment, and properties
- Policy documents, deductibles, premiums, and coverage levels
- Claim procedures and contact information for insurers
- Additional insurance maintained by vendors or 3rd parties
Adequate insurance facilitates financial recovery during and after disaster events.
Disaster recovery testing/exercises
Plans should be routinely tested to validate their effectiveness. Testing helps evaluate staff preparedness and identify plan gaps or deficiencies needing correction. Examples of exercises include:
- Tabletop exercises to walk through simulated disaster scenarios
- Simulated disaster drills or role playing exercises
- Functional testing of technical recovery procedures
- Backup restoration tests to verify information availability
- Transition tests to alternate sites to validate operational readiness
Frequent testing ensures disaster recovery remains relevant and actionable.
Employee training
Personnel training prepares staff to fulfill response roles and responsibilities outlined in the disaster recovery plan. Training should address:
- Business impact analysis results
- Emergency response procedures
- Technical recovery procedures for critical systems
- Communications methods and protocols
- Roles staff will play when disasters strike
Training develops skills and awareness to implement procedures effectively.
Plan maintenance processes
The disaster recovery plan needs ongoing reviews and updates to remain current. Plan maintenance processes should include:
- Scheduled reviews – quarterly or biannually
- Updating the plan following testing or actual disasters
- Tracking/incorporating relevant changes to IT systems, business processes, suppliers, facilities, etc.
- Version control and approvals for plan changes
- Distribution methods when plan revisions are finalized
Consistent plan maintenance keeps disaster recovery practices aligned with evolving business needs.
Conclusion
Developing a comprehensive, actionable disaster recovery plan is essential for limiting organizational risk. By assessing critical impacts through a BIA, detailing tailored procedures, communicating effectively, training personnel, testing regularly, and maintaining vigilantly, companies can implement a robust framework for protecting against disruptions. While major disasters are unpredictable, thorough preparation makes organizations far more resilient and responsive when catastrophe strikes.
